The CLIVAR / IOC-GOOS Indian Ocean Panel has been actively involved in the planning on the 50th Anniversary of the International Indian Ocean Expedition (IIOE-2), in partnership with IOC Perth Programme Office, the Scientific Committee on Oceanic Research (SCOR) and the Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER).

An IIOE-2 Reference Group was formed and between 2013-2014 refined the concept for IIOE-2 and developed an outline of scientific priorities, as well as elements of an IIOE-2 governance/coordination structure. Documentation and reports of the Reference Group meetings can be found at the IIOE-2 website, hosted by the IOC Perth Programme Office
